We all are familiar with the recorders and their functionalities. These devices are used to record and store the recorded data into various mediums like tapes, cassettes, CDs, DVDs, hard disks, and so on. The recorders in early times used to store audio files on magnetic tapes. Surprisingly, these magnetic tapes and cassettes stayed around for a long time for storing both audio and video as well.

But today, with the booming digital age, digital devices are being used for storing the audio and video both. This change has been observed over the last decade. Digital recorders are becoming a popular recording medium because it is fast and can store way too much data than magnetic tapes. Not to mention the compact and portable feature is making them even more widely accepted.

DVDs still rule the world of audio/video data storage mediums. They have a unique place in the market as a reliable data storage device. A DVD video player works well to read that stored data and display it on the monitor.

 A DVD recorder, on the other hand, is a device that records data onto a DVD, which can read data from an analog source, e.g., TV, floppy disks, video cassettes, CDS, digital cameras, and mobile phones. There also come DVD burners/writers that are capable of reading and storing data from the computer onto a DVD.

If we talk about the essential- time modes of a DVD recorder, then there are five modes— one, two, four, six, and eight hours mode. Some recorders are also with two-and-one-half-, three-and-one-half-, and four-and-one-half-hour modes. And the rule is—the smaller the mode, the better the recording quality!

Therefore, in comparison with four, six, and eight-hour modes, one- and two-hour modes are better. Needless to say, they also play well in most DVD players.

A typical commercial DVD can hold up to 130 minutes of video data, while some DVDs have two layers to hold 130 minutes of video data on each layer.
